The present invention relates to an information display device, a control method, and a program.

Technologies have been disclosed for improving the operability of mobile terminals such as smartphones and for effectively displaying content (see, for example, Patent Documents 1 and 2).

JP 2013-214164 A JP 2018-195210 A

On such mobile devices, when messages from various categories are displayed on a screen that chronologically displays the contents of notifications, such as push notifications, messages are displayed mixed together, reducing visibility and increasing the likelihood that users will miss important information.

In addition, some smartphone communication applications require a larger display area on the screen the more characters a message contains. This means that the display area varies for each message. This causes the user's eyes to be drawn to the size of the message rather than its content, increasing the possibility that the user will miss important information. Furthermore, when a message contains many characters, that one message takes up the entire display area, making it difficult to see at a glance whether there are other messages. As a result, it is difficult to know, for example, how many messages have been notified today.

Furthermore, when scrolling up and down to move between messages, it is quite a difficult operation to reach previous messages, and if the scrolling speed is too fast, the user is more likely to miss important information.

The present invention was made to solve the above problems, and its purpose is to provide technology that improves user operability and visibility.

In order to solve the above problem, one aspect of the present invention is an information display device that includes a display control unit that displays a category image indicating a category to which displayed information belongs at a predetermined position and displays a message belonging to the category indicated in the category image displayed at the predetermined position, and an operation reception unit that receives user operations, and when an operation to move the category image in a predetermined direction is received by the operation reception unit, the display control unit moves the category image in the predetermined direction and displays a category image indicating a different category at the predetermined position, and updates the displayed message to a message belonging to the category indicated in the category image displayed at the predetermined position.

In one aspect of the present invention, when the operation reception unit receives a predetermined operation in a message display area in which a message is displayed, the display control unit hides the message that was displayed in the message display area in which the predetermined operation was received, and displays content corresponding to the predetermined operation.

In one aspect of the present invention, the predetermined operation is an operation for displaying details of a message, or an operation for displaying the next message to be displayed.

In one aspect of the present invention, the message display area is a constant size regardless of the number of characters contained in the message.

In one aspect of the present invention, the display control unit is capable of displaying a list of messages belonging to one category in a list view in which the messages are displayed at a constant size regardless of the number of characters contained in the messages, and when the operation reception unit receives an operation on an operator for displaying the messages in the list view, the display control unit displays the messages in the list view.

In one aspect of the present invention, the list display includes a list of messages including messages that have been hidden by the predetermined operation, and information indicating whether an operation has been performed to display the details of the message is displayed for each message.

In one aspect of the present invention, categories include categories that can be selected by the user and categories that are always displayed to all users.

One aspect of the present invention that solves the above-mentioned problems includes a display control step of displaying a category image indicating a category to which the displayed information belongs at a predetermined position and displaying a message belonging to the category indicated in the category image displayed at the predetermined position, and an operation reception step of receiving a user operation, and when an operation for moving the category image in a predetermined direction is received by the operation reception step, the display control step is a control method that moves the category image in the predetermined direction, displays a category image indicating a different category at the predetermined position, and updates the message to be displayed to a message belonging to the category indicated in the category image displayed at the predetermined position.

One aspect of the present invention that solves the above-mentioned problems is a program that causes a computer to function as a display control unit that displays, at a predetermined position, a category image indicating a category to which displayed information belongs, and a message belonging to the category indicated in the category image displayed at the predetermined position, and an operation reception unit that receives user operations, and when an operation to move the category image in a predetermined direction is received by the operation reception unit, the display control unit moves the category image in the predetermined direction, displays a category image indicating a different category at the predetermined position, and updates the message to be displayed to a message belonging to the category indicated in the category image displayed at the predetermined position.

The present invention provides technology that improves user operability and visibility.

Figure 1 is a diagram showing an example of the configuration of a distribution system 10 including a user terminal 300 as an example of an information display device according to an embodiment of the present invention. The distribution system 10 according to this embodiment is, as an example, a system that distributes local government information, and therefore the user terminal 300 also displays local government information, but the distributed information is not limited to information about the local government.

The distribution system 10 is composed of a distribution device 100, a local government device 200, a user terminal 300, and a network NW. The network NW may include a LAN (Local Area Network), a WAN (Wide Area Network), the Internet, a mobile communication network, a cellular network, etc.

The distribution device 100 distributes the local government information registered by the local government device 200 to the user terminal 300. The local government device 200 is a device operated by a local government employee, and registers the local government information to be distributed to the user terminal 300 in the distribution device 100. The user terminal 300 is a terminal such as a smartphone used by residents of the local government.

Figure 2 is a diagram showing an example of the functional configuration of the user terminal 300. The user terminal 300 includes a control unit 110, a communication unit 120, a display unit 321, an operation unit 322, and a storage unit 130. These components are realized by, for example, a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by cooperation between software and hardware. The program may be stored in advance in a storage device (a storage device having a non-transient storage medium) such as an HDD (Hard Disk Drive), an SSD (Solid State Drive), or a flash memory, or may be stored in a removable storage medium (non-transient storage medium) such as a DVD or a CD-ROM, and may be installed by mounting the storage medium in a drive device.

The communication unit 120 is a communication interface that connects the distribution device 100 to the network NW. The communication unit 120 communicates with the local government device 200, the user terminal 300, and the like via the network NW. For example, the communication unit 120 can be connected to a 4G line such as LTE (Long Term Evolution), a 5G line, a wireless LAN, Bluetooth (registered trademark), and the like.

The display unit 321 displays various information to the user in accordance with the control of the control unit 310. The display unit 321 is configured, for example, with an LCD (Liquid Crystal Display) or an organic EL (Electro Luminescence) display. The operation unit 322 detects user operations and notifies the control unit 310 of the detected operations. The operation unit 322 is configured, for example, with a touch panel or hard keys.

The memory unit 330 includes a storage device such as a flash memory. The memory unit 130 stores, for example, message information 331. The message information 331 is information indicating a message to be displayed on the user terminal 300. FIG. 3 is a diagram showing an example of the message information 331. As shown in FIG. 3, the message information 331 is information in which a message ID, update date and time, read flag, category, and message body are associated with each other.

The message ID is information that uniquely identifies the message information. The update date and time is the date and time when the message information was updated. Note that the update date and time is not limited to the date and time when an existing message was updated, but also includes the date and time when a new message was issued. The read flag is a flag that indicates whether or not the details of the message have been displayed on the display unit 321 by the user. If the details of the message have been displayed on the display unit 321 by the user, the message is marked as read, and if the details are not displayed, the message is marked as unread. The category indicates the category to which the message belongs. Examples of categories in this embodiment include child-rearing, sightseeing, and events. The message body is information that indicates the message content itself.

The control unit 310 in FIG. 2 controls each unit of the user terminal 300. The control unit 310 includes a display control unit 311 and an operation reception unit 312. The display control unit 311 displays a category image indicating the category to which the displayed information belongs at a predetermined position, and displays a message belonging to the category indicated in the category image displayed at the predetermined position on the display unit 321. The operation reception unit 312 receives user operations notified by the operation unit 322. An actual display example by the display control unit 311 will be described.

Fig. 4 is a diagram showing a display example. A notification area 415, a calendar area 416, and a service list area 417 are displayed on a home screen 400 shown in Fig. 4. In addition, a category image 401, a badge 402, movement buttons 403 and 404, a location image 405, a message display area 406, a home button 407, and a list button 408 are displayed on the home screen 400.
The notification area 415 displays a message display area 406 showing messages belonging to a category shown in the category image, etc. When there are multiple messages that can be displayed in the message display area 406, they are displayed so as to overlap, as shown by the reference numeral 410. In the case of this embodiment, when two messages can be displayed, two message display areas 406 are displayed so as to overlap. When three or more messages can be displayed, three message display areas 406 are displayed so as to overlap. For example, even when five or more messages can be displayed, three message display areas 406 are displayed so as to overlap. Also, as shown in FIG. 4, the message display area 406 has a constant size regardless of the number of characters included in the message.

The calendar area 416 displays a calendar showing some kind of schedule. In the case of FIG. 4, it shows the scheduled date for garbage collection. In addition to garbage collection, scheduled events can be displayed on the calendar by selecting "Events" shown on the calendar. Also, by selecting "View list", a list of scheduled dates is displayed. The service list area 417 displays various services provided by the government. In the case of FIG. 4, the bottom half is hidden, but the entire service list area 417 can be displayed by moving the area including the home button 407 (described later) downward.

Home button 407 is a button for displaying home screen 400 shown in FIG. 4. List button 408 is a button for displaying a list screen (described below) that displays a list of messages belonging to one category in a list display in which the messages are displayed at a fixed size regardless of the number of characters contained in the messages. List button 408 is an example of an operator for displaying in list display.

In FIG. 4, category image 401 is an image showing the category of the message displayed in message display area 406. In the case of FIG. 4, "Sightseeing/Events" is displayed as the category. Also, as shown in FIG. 4, category image 401 is displayed at a predetermined position (approximately in the center in the left-right direction). Category image 401 is movable in a predetermined direction (horizontal direction (either leftward or rightward). Therefore, category images 401 are virtually arranged in a horizontal direction. Note that the predetermined direction does not necessarily have to be horizontal, and may be vertical or other directions. Also, the movement of category image 401 may be in any manner, for example, it may be a continuous movement in the horizontal direction or a discontinuous jump movement in the horizontal direction.

When a user touches the move buttons 403 and 404 to accept an operation to move the category image 401, the display control unit 311 moves the category image in a predetermined direction and displays a category image indicating a different category at a predetermined position. The display control unit 311 then updates the message to be displayed to a message belonging to the category indicated by the category image displayed at the predetermined position.

Specifically, the left adjacent category image 401L indicates a category image that is displayed at a predetermined position when an operation is performed to move the category image currently displayed at a predetermined position to the right (the user touches the move button 404). When the move button 404 is touched by the user, the message is updated to belong to the category indicated by the left adjacent category image 401L.

The right adjacent category image 401R indicates a category image that is displayed at a specified position when an operation is performed to move the category image currently displayed at a specified position to the left (the user touches the move button 403). When the user touches the move button 404, the message is updated to belong to the category indicated by the right adjacent category image 401R.

In this embodiment, the operation of the user touching the move button 403 or the move button 404 is taken as an example of an operation for moving the category image 401 in a predetermined direction, but other examples of operations include a flick operation in the left and right directions.

Badge 402 indicates the number of messages that can be displayed in message display area 406. In the case of FIG. 4, three messages can be displayed. Position image 405 indicates the horizontal position of the category being displayed. Position image 405 is shown with large dots (referred to as "large dots") and small dots (referred to as "small dots"). The number of dots included in position image 405 is the number of categories that can be displayed. FIG. 5 is a diagram for explaining position image 405. An enlarged position image is shown in FIG. 5.

The number of dots included in the position image shown in FIG. 5 is 7, so the number of categories that can be displayed is 7. The large dot indicates the horizontal position of the currently displayed category. In FIG. 5, the large dot is the fourth from the left end or the fourth from the right end, so the horizontal position of the currently displayed category is the fourth from the left end or the fourth from the right end. Furthermore, both the large dot and the small dot are displayed as either a black circle or a white circle. A black circle indicates that there are no messages that can be displayed in the message display area 406. A white circle indicates that there are one or more messages that can be displayed in the message display area 406. In this way, black and white circles are used, but since the position image 405 in FIG. 4 is small, it is represented in FIG. 4 by only black circles for convenience.

The size of the circle allows the user to check at a glance the horizontal position of the currently displayed category. Furthermore, depending on whether the circle is black or white, the user can also check at a glance whether there is a message. Note that in this embodiment, the size and color of the circle are used as a way to distinguish the position and the presence or absence of a message, but this is not limited to this, and any distinguishable way may be used.

Returning to FIG. 4, the message display area 406 is provided with a next button 411 and a details button 412 that can accept predetermined operations. The next button 411 is a button for displaying the next message if there is a next message to display. The next button 411 is also displayed if there is no next message to display. The details button 412 is a button for displaying details of the message. When the next button 411 or the details button 412 is touched, the currently displayed message is hidden.

The details button 412 is a button for displaying a details screen showing more detailed content than the message displayed in the message display area 406. The message area 406 shown in FIG. 4 is a fixed size regardless of the number of characters in the message. Therefore, all messages less than a certain number of characters can be displayed, but all messages more than the certain number of characters cannot be displayed.

In this embodiment, therefore, it is possible to display a details screen that includes all messages. FIG. 6 is a diagram showing an example of a details screen. Images and links are not displayed in the message display area 406, but as shown in details screen 420, images 422 and links 423 can also be displayed on the details screen. X button 421 provided on the right side of the details screen is a button for closing the details screen. When the user touches X button 421, the home screen shown in FIG. 4 is displayed.

Next, the next button 411 shown in FIG. 4 will be described. When the next button 411 is touched on the home screen 400 shown in FIG. 4, the next message is displayed. FIG. 7 is a diagram showing an example of a home screen 430 on which the next message is displayed. As shown on the home screen 430, the badge 402 shows a "2", which is one less than the "3" displayed on the home screen 430. Furthermore, in the message display area 406, the number of messages is reduced by one from three, and the two message display areas 406 are displayed so that they overlap.

On the home screen, the message display area 406 has a fixed size regardless of the number of characters, so the more characters in a message, the larger the display area on the screen will not be. This means that the user's eyes are naturally drawn to the contents of the message, reducing the possibility that the user will miss important information. Furthermore, even if there is a message with a large number of characters, it is displayed at a fixed size, so one message does not occupy the display area, making it possible to check at a glance whether there are other messages. Additionally, overlapping message display areas 406 and badges 402 also make it possible to check at a glance whether there are other messages.

In addition, on the home screen, the user can view details about a message that interests the user by pressing the details button 412. On the other hand, for a message that the user is not particularly interested in, the user can display the next message by pressing the next button 411.

On the home screen 400, if the next button 411 is continuously touched, eventually there will be no messages to display. FIG. 8 is a diagram showing an example of a no-message home screen 440 when there are no messages to display. On the no-message home screen 440, a character string 441 indicating that there are no messages to display (All notifications have been checked. If you wish to read them again, tap "View list") and a list button 442 are displayed. The list button 442 has the same function as the list button 408. In other words, when the list button 442 is touched, a list screen is displayed.

Figure 9 is a diagram showing an example of a list screen. List screen 500 displays category tabs 501, display selection radio buttons 502, subject display area 503, and read/unread display 504. Category tab 501 is a tab that allows the user to select a category. The selected tab is displayed approximately in the center in the horizontal direction. The subjects of messages that belong to the category corresponding to the selected tab are displayed in a list.

The display selection radio buttons 502 are radio buttons for selecting the subject to be displayed in the subject display area 503. "All" in the display selection radio buttons 502 is a button for displaying the subjects of all messages, not just those that have been read or unread. "Read only" is a button for displaying the subjects of messages that have been read. "Unread only" is a button for displaying the subjects of unread messages.

In addition to the subject, the subject display area 503 displays the update date and time and a read/unread indicator 504. The read/unread indicator 504 shows "read" when the details of the message with this subject are displayed, and shows "unread" when the details of the message are not displayed. When the user touches any of the displayed subject display areas 503, a details screen corresponding to the touched subject display area 503 is displayed.

As shown in FIG. 9, the display control unit 311 can display a list of messages belonging to one category in a list display that displays the messages at a constant size regardless of the number of characters contained in the messages. In this way, the more characters a message has, the larger the display area on the screen will not be, so the user's eyes will naturally be drawn to the contents of the message, reducing the possibility that the user will miss important information. Furthermore, even if there is a message with a large number of characters, it is displayed at a constant size, so one message does not occupy the display area, making it possible to check at a glance whether there are other messages.

In the above-described embodiment, the category to be displayed may be appropriately selectable by the user. Also, a category that must be displayed to all users may be provided. That is, a category that can be selected by the user and a category that must be displayed to all users may be provided. FIG. 10 is a diagram showing an example of a selection screen for categories to be displayed. In this selection screen 600, "Important Notice" is also shown as a category that must be displayed to all users. As shown in FIG. 10, a check box 601 is provided for each category other than "Important Notice". Information indicating the category selected by the user on the selection screen 600 is stored in the storage unit 330. The display control unit 311 controls to display messages belonging to the category selected by the user among the categories of the message information 331. By providing a category that must be displayed to all users, the distribution device 100 can easily distribute messages that the user wants to display to all users. In addition, the user can recognize that the category that must be displayed to all users is a special category, so that overlooking of messages can be suppressed.

Next, the process flow will be described using a flowchart. FIGS. 11 and 12 are flowcharts showing the process flow of the user terminal 300. In FIG. 11, the user terminal 300 acquires new message information that has not been acquired at this time from the distribution device 100 and displays the home screen 400 (step S101) prior to displaying the home screen 400. The acquired message information is stored in the storage unit 330 described above. The category image displayed on the home screen may be the one that was last displayed the previous time, or may be set as a default. The message information may also be acquired by a push notification from the distribution device 100.

The operation reception unit 312 determines whether an operation to move the category image in a predetermined direction has been received (step S102). If an operation to move the category image in a predetermined direction has been received (step S102: YES), the display control unit 311 moves the category image in the predetermined direction (step S103). Next, the display control unit 311 displays, at a predetermined position, a category image indicating a category different from the category of the category image displayed before the operation was received (step S104). The display control unit 311 updates the message to be displayed in the message display area 406 to a message belonging to the category indicated by the category image displayed at the predetermined position (step S105), and returns to step S102.

If an operation to move the category image in a predetermined direction is not accepted in step S102 (step S102: NO), the operation acceptance unit 312 judges whether or not a touch to the details button 412 has been accepted (step S106). If a touch to the details button 412 has been accepted (step S106: YES), the display control unit 311 displays a details screen (step S107). If the operation acceptance unit 312 accepts a touch to the X button 421 (step S108: YES), the display control unit 311 displays the original message (step S109) and returns to step S102.

In step S106, if a touch to the Details button 412 has not been accepted (step S106: NO), the operation acceptance unit 312 determines whether or not a touch to the Next button 411 has been accepted (step S110). If a touch to the Next button 411 has been accepted (step S110: NO), the display control unit 311 determines whether or not there is a next message (step S111). If there is a next message (step S111: YES), the display control unit 311 displays the next message (step S112) and returns to step S102. If there is no next message (step S111: NO), the display control unit 311 displays the no-message home screen 440 (step S113) and returns to step S102.

In the above step S110, if a touch to the next button 411 has not been accepted (step S110: NO), the operation acceptance unit 312 determines whether or not a touch to the list button 408 has been accepted (step S114). If a touch to the list button 408 has not been accepted (step S114: NO), the process returns to step S102. If a touch to the list button 408 has been accepted (step S114: YES), the process proceeds to step S201 in FIG. 12.

In FIG. 12, the display control unit 311 displays the list screen 500 (step S201). The operation reception unit 312 determines whether or not a touch on the category tab 501 has been received (step S202). If a touch on the category tab 501 has been received (step S202: YES), the display control unit 311 displays a list screen of messages belonging to the touched category (step S203) and returns to step S202.

In step S202, if a touch on the category tab 501 has not been accepted (step S202: NO), the operation acceptance unit 312 determines whether or not a selection of "All" on the display selection radio button 502 has been accepted (step S204). If a selection of "All" on the display selection radio button 502 has been accepted (step S204: YES), the display control unit 311 displays a list screen of the subject lines of all messages (step S205) and returns to step S202.

In step S204 above, if the selection of "All" on the display selection radio button 502 has not been accepted (step S204: NO), the operation acceptance unit 312 determines whether or not the selection of "Read" on the display selection radio button 502 has been accepted (step S206). If the selection of "Read" on the display selection radio button 502 has been accepted (step S206: YES), the display control unit 311 displays a list screen of the subjects of messages that have been read (step S207), and returns to step S202. Note that whether or not a message has been read can be determined by referring to the read flag.

In step S206 above, if the selection of "Read" on the display selection radio button 502 has not been accepted (step S206: NO), the operation acceptance unit 312 determines whether or not the selection of "Unread" on the display selection radio button 502 has been accepted (step S208). If the selection of "Unread" on the display selection radio button 502 has been accepted (step S208: YES), the display control unit 311 displays a list screen of the subjects of unread messages (step S209) and returns to step S202. Whether or not a message is unread can be determined by referring to the read flag.

In step S208 above, if the selection of "Unread" on the display selection radio button 502 has not been accepted (step S208: NO), the operation acceptance unit 312 determines whether or not a touch on the home button 407 has been accepted (step S210). If a touch on the home button 407 has been accepted (step S210: YES), the display control unit 311 displays the home screen (step S221) and returns to step S102 in FIG. 11. If a touch on the home button 407 has not been accepted (step S210: NO), the process returns to step S202.

As described above, according to this embodiment, when an operation to move a category image in a predetermined direction is received, the display control unit 311 moves the category image in the predetermined direction and displays a category image indicating a different category at a predetermined position, thereby improving user operability. In addition, the message to be displayed is updated to a message belonging to the category indicated in the category image displayed at the predetermined position, thereby improving user visibility.

In addition, in this embodiment, when an operation to display details of a message or an operation to display the next message to be displayed is received, the display control unit 311 hides the message that was displayed in the message display area where the operation was received, and displays content according to the specified operation. In this way, it is possible to display details of a message or the next message with a single operation, thereby improving operability for the user.

In addition, the message display area is a constant size regardless of the number of characters contained in the message, which improves visibility for the user compared to when the size varies. Furthermore, the display control unit 311 can display a list of messages belonging to one category in a list view that displays the messages in a constant size regardless of the number of characters contained in the message, which improves visibility for the user compared to when the size varies. In addition, the list view displays information for each message that indicates whether an operation has been performed to display the details of the message (unread, read), so that it is possible to check at a glance whether the user has displayed the details.

Note that some or all of the above functions may be realized as an integrated circuit such as an LSI (Large Scale Integration). Each of the above functions may be individually processed, or some or all of the functions may be integrated into a processor. The integrated circuit method is not limited to LSI, and may be realized by a dedicated circuit or a general-purpose processor. Furthermore, if an integrated circuit technology that can replace LSI appears due to advances in semiconductor technology, an integrated circuit based on that technology may be used.
